3.2.5.3.
Ping Request Program is a program that sends Ping Request to certain destination. It uses ICMP protocol
message on IP protocol and made with ping_request().
ping_request() is created with form similar to Ping program in DOS command prompt. It sends Ping request
to destination after analyzing and processing the options.
Both domain name and IP address can be used as destination address for Ping request. In case of using
domain name, domain name is changed into IP address using gethostbyname() or DNS. With the changed
IP address the Ping request is sent.
When IP address is used with „-a‟ option, domain name can be obtained through gethostbyaddr() from DNS
Server and the Ping request is sent to the IP address. When IP address is used without the „-a‟ option, Ping
request is sent to input IP address without the connection with DNS.
gethostbyname(), gethostbyaddr() is DNS-related functions. For further information, refer to
DNS
<Fig 3.8> creates tokens of inputs of Command, Option, and Option Value and decides the related Bit of
Argument Flag(PingArgsFlags).
<Fig 3.9> calls ping() based on relevant option and option after checking the validity of command, option,
and option value with bits of argument flag. ping() sends Ping request message to certain destination and
process the ICMP message which is received from any destination.
Client. <Fig 3.8> and <Fig 3.9> are processing procedures of ping_request().
